To zZZ whom it may concem:

Be it known that I, ALEXANDER MCCUL' LoCH, a citizen of the Dominion ofCanada, residing at Govan, in the county of I-lumboldt and Province ofSaskatchewan, have invented certain new and useful Improvement-s inGarage Doors', of which the following is a specification. f v

This invention relates to improvements in..

garage doorl operating means and-provides an. automatic means wherebythe doors will` be swung open on the approach of an automobile. f Y Y vt The/object of my invention is to provide a means whereby doo-rs willbe automaticallyy thrown open on the approach of an automobile. .Y i lA-urther object of my invention is to provide a means for locking v,saiddoors inopen positionso lthat ,they will not slam` shut lwhentheautomobile is only partly in; the garage.

A further object is to provide a means for releasing the locking meanswhen the rear of the automobile has passed the locked doors.

A still further lobject is to provide a means for releasing the lockingmeans when the automobile is beingtaken out of the garage and it haspassed out through said doors.

With these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts as will behereinafter fully described, illustrated in the accompanying drawings,and pointed out in the claim hereunto appended.

Figure 1 is a detail plan view.

Figure 2 is a detail side view partly shown in section.

lFigure 3 is a `detail -view of the spring operating means.

Figures 4 and 5 are detail views of the door operating means.

Figure 6 is a detail view of the lug hinging the upper end of the saiddoors.

Figure 7 illustrates the unlocking means Jfor said door-s while in openposition.

Figure 8 illustrates the automatic releasing means for said doorsfwhilein open position. v

Referring to the drawings like numerals designate like parts in thevarious drawln s.

I() indicates the garage frame. e 11 indicates floor. 12 indicates theapproach to the garage in which are provided I. slots m 14. 15 andlindicate members hingedlycoin f shaft 20 having'its upper end threadedas at y21v adapted to be received into thev socket djustably positionedon 'theshaft 195.vr y1s a double arm member 22. Itsinner end is, ,5; l

hingedly connected to-an arm 23.k rlhe op#` v posite end of the arm 23is hingedly con-- necte'din, a` yU-shaped member,24. -The` -U-shapedmember 24- is provided with a transverse opening and is reciprocallypo-yA sitioned on a rod 2,5. The .rod 25 is suiti ably mounted on aframe 26 in brackets 27..:

.Positionedon the rod 25 isla coil spring v28 adapted'to tension theU-shaped member 24 as indicated by the arrow in Figure., The 'liopposite endy of the double .arm 4 22 isconnectedto an arm29, which isprovidedwit-h i., Y. a turn buckle 30 yfor' adjusting it tovariousVlengths. '80

suitably/Q positioned in the. .frame 1o, fr y provide rods 32,'havingtheir upperends l suitably attached. tothelower endofthe` rod 32 isprovided with a radially vextending arm 34, the free end of whichattaches to ing of an automobile, the wheels" will be doors as at 33 sothatfthe door willhinge thereon. The door is hinged at its upperlcornervas shown at'33 in igure `6.; The

16. These members may bepressed down at their upper end, so that thesockets 18 will turn the 'threaded portion 21 of the shaft 20. This willturn. the double arm v 22 'so that the arm 23 will pull the U-shapedmember 24 .in the direction'of the arrow, Figure 3, while the arm 29will push the arm 34 lin the direction of the arrow, Fig` ure 4, whichwill turn the ldoors'from closed to open position. In garage doors,there is generally a locking means at the bottom of the door such as apin 48 which can be easily pulled up from the inside of the door.

The member 16 is provided at its hinged end with a. plate 40, having anopening 41 which opening extends. through the member f 16. 42 is a tripmember tensioned upwardlyby a coil spring 43 suitably positioned in theopening 41. The lower end of the trip member 42 is adapted to strike oneend of the bell crank 44. The opposite end of the bell crankis attachedto a cable 45, which cable is attached at its opposite end to a bellcrank 46,. The opposite, end of this bell crank 46 is adapted to pressupwardly on a tension pin 47. The pin 47 is positioned under the openingin which the pin 48 of the door is positioned when the pinl 48 is inlocked position. As the automobile passes'o'ver the, member 1G, it tripmember 42 downwardly, which will act through theirespective parts inpressing the lockl pin 48 of the door upwardly from its locked position.vThe weight of the automobile on the members l5 vand 16 will now turnthe doors open as previouslykdescribed. Suitably positioned on the floorl1 inside the garage, provide a plate 50, having a cer'itral openingover an opening in fthe floorll. A plate 51 is positioned on the Aunderside of this opening andA has an kopening therein. l y

52 are'braclrets supported from said plate 51, in'k which are 'hingedlypositioned bell cranks 58 and 54.Y 1When the doors are opened, the pin48 carried by one of the doors will drop into the opening through thevplate'() and to provide a means for disengagingthe pin48 with the plate50, l provide a pin 551 tensionally held in the floor andfbeingprovided-with a flange near its lowerend; The bell vcrankv 54 has acable attached to one endwhile its opposite end is bifurcated and fitsover the flangedv end of-pin 55.- 'This cable v56 is attached to asuitable trip member 57 similar to trip member'42. This trip member ispositioned to be passed over by the wheels ofthe automobile when inthegarage and will cause the pin to be pressed upwardly, thus diswill:press the,

engaging the locking pin 48 of the door, so that the tension spring 28will re-act to close the doors.

After taking the automobile out, I provide a means whereby the travelofthe automoi bile willautomatically release the pin 48 and allow thedoors to close. Referring to Figure 8,' provide a trip member 6() havingtensioned pins 6l and 62 positioned under each respective side. When theautomobile travels up the approach, ythe member 60 is lease the pin 48allowing the doors to closer What I claim as new is: In l combinationwith a pair of garage doors, a pin locking means at'the lower ends ofone of said doors, an inclined platform to;

said doors depressible` longitudinal members., hingedly connected at oneend 1n said me clined platform, release means in one of saidlongitudinal members for releasing said locking pin, a means for openingsaid doors, a

means for retainino1 said doorsin open posi` tion, a means on t e otherof said longitu-` dinal members for disengaging said retaining means,and a means on the other side of the door for releasing said retainingmeans.

ln testimony whereof, l my signature in the presence of two witnesses.
